Sustainable outdoor lighting system for use in environmentally photo-sensitive area
First Claim
1. An environmentally sensitive outdoor lighting system, comprising:
- a first light source that produces monochromatic light with a peak wavelength between about 580 nm and about 615 nm;
a second light source, wherein the second light source is a polychromatic LED light source producing a green-tint white light, and wherein illumination of both the first light source and the second light source produces a white light with a color rendering index of about 75 or above;
a control system electrically coupled to the first light source and the second light source; and
an imaging system integrated with the control system and providing an input to the control system, wherein the imaging system comprises a processor having image-recognition logic to differentiate between a target and another non-target moving object,wherein the control system is programmed to illuminate the first light source in a standby operational mode, and illuminate both the first light source and the second light source when the imaging system detects a target within an illumination area; and
a communications module coupled to the control system, wherein the communications module provides external commands to the control system.

Abstract
Provided herein are systems and methods for outdoor lighting, which generally include two or more light sources. One light source is a monochromatic light source producing a light with a peak wavelength of about 580 nm or above. A second light source is a polychromatic light source producing a green-tint white light. During a standby operational mode, a control system maintains the first light source illuminated. The control system, which includes an integrated imaging system, illuminates both the first light source and the second light source when the imaging system identifies a target in an illumination area. Methods of preparing and using such outdoor lighting system are also provided.
